Conversion rate optimization for Shopify brandsTry it free for 14 days

Find what stops shoppers buying.

AI conversion rate optimization for Shopify stores. HI Engine finds where your store loses sales, builds the fix in your theme and A/B tests it.

Brands moving with HI

What HI does on a product page.

An illustrative example, not a real store: the problem HI found, the fix it built and the approval it waits for.

  1. Problem found

    Shoppers aren’t sure the serum suits their skin type.

  2. Fix built

    A skin type guide next to Add to cart, on a draft theme.

  3. You approve

    Preview it on your store, then approve it for testing or ask for changes.

Customer story: Fulton

“HI Engine feels like magic; the opposite of AI slop. Building and launching CRO tests is so easy, I keep thinking, ‘Wait, it can actually do that?!’ At Fulton, it’s meaningfully impacted our conversion rate, engagement rate, and AOV.”

How it works. You approve every change.

See the full process

  1. Identify

    HI reads your Shopify data, analytics and customer feedback to find where shoppers get stuck.

  2. Build

    It writes the fix into your theme and puts it on a draft theme for you to preview.

  3. Approve

    You review the change on your own store. Nothing goes live until you approve it.

  4. Test

    HI A/B tests the change against your current page, so you see whether it helped.

Reads the tools you already run.

All integrations
  • Shopify
  • Klaviyo
  • Google Analytics 4
  • Click Context
  • Zigpoll
  • Intelligems
  • Slack

Nothing goes live without your approval.

You see every change before your customers do, and you can undo it in one click.

  • Preview

    Every change goes to a draft theme first. Preview it in your own store.

  • Approval

    Nothing is published until you approve it. Approved tests can be cancelled until they start.

  • Rollback

    Every change is logged. Winners stay; the rest roll back in one click.

Technical details

Changes are written into your theme as native Liquid, JSON and CSS, the same code your developers would write. No page-builder app, no injected scripts, no third-party layer on your storefront. Shopify Theme Check validates each change, and full execution logs record everything HI does. SOC 2 is on our roadmap.
